To all dbllom it may concern:

Be it known that I,'JOHN V. LAnnEY, a citizen of the United States, residing at Arlington, inthe county of Hudson and State of New Jersey, have'invented certain new anduseful Improvements in -Wind-Shields. for

clear,; and exact specification.

T hlS invention relates to wind shields for vehicles, and has reference to a shield for dej Vehicles, of which the following is a full,

motion of a vehicle away from the eyes of the driver or other person in the vehicle,

whereby theuse of glass or other transparent media .may' be obviated.

The use of lass and other forms of transparent wind s -ields in vehicles is objectionable because, such devices collect rain, snow, dampness, etc., and obscure the view, frequently causing accidents and damage by reason of the imperfect view obtained by the drivel; According to this invention, 1 have provided a deflector which will cause the current of air produced by the motion of the vehicle to be deflected preferably upward in uch a direction as to pass over the head of the driver and not mto his eyes, thereby permitting glass or transparencies to be dispensed with and permitting a'clear view irrespective of the condition of the weather.

The invention is particularly useful on the cabs of locomotives where the best'possible facilities for observationare necessary, and likewise is applicable to other vehicles such as automobiles, and also boats, and 'in all places where observations mustbe made in the face of strpng currents of air.

The invention with reference to several forms thereof is shown in the accompanying drawings, wherein e I Figure 1 is a front view of an apparatus embodying the invention applied to the cab of alocomotive Fig. 2 is a side view.

1 represents a curved plate adapted to be supported on a vehicle in any suitable manher and provided with sides 2 for confining the air currents so that after striking the deflector 1 they will be deflected upwardly and rearwardly. The cross section of the deflector 1 may be of various forms, as may also the shape and angle of the sides 2 relatively to the plate 1. constructed according to this general princi leis to create an upward current of air w ch willjdeflect the horizontal air currents 1 which normally would pass over the top of The action of such a deflectorthe deflector 1 into-an observers eyes, upwardly and .rearwardly. There is thus a space directly above and behind deflector l of comparative quiet, no matter how strong the horizontalair currents due td the speed of the vehicle'or wind may be. If the eyes of thedriver be in this uiets ace immediately above and behind t e de ector, an unobstructed view can be had without requiring a transparent glass or other medium, and his eyes will not be bothered by the air currents. As herein shown, I have embodied this broad idea of a deflecting shield in an apparatus. capable of being applied to a locomo- =tive cab, as shown in Figs. 1 and 2, wherein the deflectorl is pivoted at 4 so as to be adjustable by means of a rod 5 from within a hood 6, the latter having a side window 7 and a roof 8. The roof 8 may be curved downwardly as at 9 with its lower edge somewhat behind the upper edge of deflector 1 to form the observation space 10, at which no air currents will exist, the air currents being deflected upwardly from the surface of the "plate and passing across the aperture 10 and then rearwardly along the roof 8.

11 is a'slide mounted under the roof 8 and capable of being moved to vary the width of the aperture 10.

The deflector 1 will be adjusted in position according to the particular conditions of wind velocity or the speed of the vehicle so as to assume a more vertical or horizontal position as may be desired. v

By the use of this invention, it will be seen that the necessity for using glass orother transparencies to protect the eyes from wind is avoided, and the observation space above the deflector 1 will not be liable to obstruction, conse uently preventing accidcntsand damage suc as have happened where engine drivers have been blinded.

The particular form of deflector and its cross section, size, dimensions, etc, will, of course, be capable of wide variation, according to conditions under which the invention is to be used, and I do not restrict myself to any particular form, shape and dimensions.

Having thus described my invention, I declare that what I claim as new and desire to secure by Letters Patent, is r 1. A wind deflector comprising a curved late, sides, and a top somewhat above and behind the curved. plate and separated from the edge of the plate to form an observation space.
